Benefits of technology

The present invention provides a way to make power saving mode in wireless communication more flexible, while also preventing communication delay and reducing power consumption.

Problems solved by technology

Because the notification of the TIM or the DTIM is dependent upon a transmission period of the beacon, there is a possibility that a data transmission delay will occur based on at least the interval of the beacon and the DTIM interval.
In this way, when shifting between the awake state and the doze state occurs frequently in the process of communication of the same session, a communication delay occurs due to overhead of the change in state.
Also, when the amount of data communicated becomes large, delays in communication occur markedly.

Abstract

An information processing apparatus includes a wireless LAN control unit which performs a wireless communication, a power mode setting unit which accepts a setting instruction for setting a power saving mode to be OFF or ON from a user, and a power saving mode setting storage unit which holds a setting that is set for the power saving mode, and a table storing a setting for turning the power saving mode off / on in association with a protocol used in a wireless communication. In case the power mode setting unit holds the setting for setting the power saving mode to be ON, the information processing apparatus controls whether or not to turn on the power saving mode based on a protocol used in the wireless communication and a setting of the power saving mode stored in the table in association with that protocol.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an information processing apparatus, a method of controlling the same, and a storage medium.[0003]2. Description of the Related Art[0004]In recent years, many electronic devices equipped with a wireless LAN terminal in compliance with an IEEE 802.11 standard have been commercialized, and one of these is an image forming apparatus. Similarly to conventional wireless LAN terminals, a wireless communication unit of the image forming apparatus connectable to a wireless LAN has a power saving mode for reducing an amount of power consumption. In general, when the wireless LAN terminal enters the power saving mode, a state in which data can be received continuously from an access point is exited (for example, refer to Japanese Patent Laid-Open No. 2002-300175). Specifically, as shown in FIG. 1, data can be received at an arbitrary timing from the access point in a case where the power saving mo...
